To all whomit may concern ")0 it known that I, Josnrrr BECKER, a

citizen of the United States, residing in littsbii' i, in the county orAllegheny and tf'tate o Pennsylvania, have lnventeo. a

new and useful Improvement in Coke-Oven ilmoke-liischurging Means, ofwhich the ibllorsim: is a specification.

This invention relates in general to coking plants and has for itsessential obiect thcprovision of an eiilcient means tor taking care ofthe smoke incidental to the charging of a heated coking oven whichpermits the smoke oiitake to continue until leveling operation has beeneii'ected, therebi' insuring proper discharge or smoke "from a coke evenduring the entire period or charging and preparing the charge within theoven for coking, with the result that trrip iiing oi smoke within theoven is eliminated I A further highly important ob1ect oi the i is theprovision of means tor (llS- the smoke either into a smoke the usual gascollecting main, desired, the valuable by-products main or n so that. 1

carried along" with the gas laden smoke may he recwrered with the gasevolved in the coking of the charges within the several hambers oi" theplant and discharged into collecting main.

convenience the present description will be confined to this use of theinvention; features 01" construction are however readily susceptible ofother valuable applications and consequently it is manifest that thescope of the invention is by no means confined to the specific use andthe specific embodiment herein described.

By referring to the drawings, there is indicated at 11 a fragmentarysection taken longitudinally through an oven or coking chamber of a cokeoven battery, or plant, of the by-product type. It will be under stoodthat the coke oven battery may be of the usual construction, embodyinggenerally a plurality of coking chambers arranged side by side andextending transversely of the battery and provided with the usualalternating heating walls having plane tlues intermediate adjacentcoking chambers. Each coking chamber or oveh is provided with'a set ofcharging holes 12 and also in the present instance, with a set of smokeoutlets 13, the several smoke outlets being each independent of thecharging holes. The several charging holes 12 oi each oven chamber arearranged at intervals therealong. as clearly shown in Fig. 1, and theindependent smoke outlets 18 are disposed in alternation with thecharging holes. According to this arrangement, a smoke outlet is locatedbetween each pair oi adjacent charging holes, with the result that smokemay escape from the oven chamber durins. charging and until the levelingoperation has been completed, through outwhich are intermediate theseveral mounds of coal deposited in the oven by the oharg ig apiiiratus. thereby eliminating trapping oi? smoke in the oven andinsuring complete oil-take ot the smoke. during the charging andleveling interval. The charging holes 12 and the smoke outlets 13respectively extend through the top 14 of the coking chamber or oven andmay each be provided with suitable closures, not shown, but of aconstruction well known in the art, for closing the top of the ovenduring the coking operation. It will be understood that the closures ofthe several charging: holes and smoke outlets are removed. during thecharging operation. At one side of the coke oven battery, preferably thepusher side, there is provided a collecting main 15, the lattercommunicating with ascension pipes 16 extending i'ipwardly from gasoutlets 17 formed in the top let ot the respective ovens or chambers 11.The gases evolved from the coking oi? the charge of coal in each oven orchamber pass np\.vardly through the ascension pipe and thence into thecollecting main 15, through which such gases pass to the by-productrecovery up paratus.

The charging of the individual coking chambers or ovens of a coke ovenbattery is, in the present instance, effected by means of a lorry caradapted. to run on tracks 17 extending lengthwise across the top of thebattery or series of ovens, whereby the lor y car may be moved intocharging position with respect to any of the chambers or ovens to becharged. In its construction, the lorry car embodies a suitable supporing frame work for the several. instrumentalities mounted on the car,the entire frame and other mechanism being supported upon wheels 18journaled in suitable bearings 19 supported by the bottom of the frame.The lorry car or truck, in the present instame, provided with four coalhoppers 19 of general funnel shape and supported by the framework in anysuitable manner. The bottoms of the hoppers are located at spacedintervals and are adapted to be positioned directly over the tourcharging holes 12, as shown more particularly in Fig. 1. Each hopper isnormally closed at its bottom by a slide 20 beneath whh h is located adepend-- ing chute 21 provided with an encircling extensible sleeve 22adapted to be projectezl into registry with an appropriate charging hole12 of a coking chamber or oven 11. lVhenever a slide 20 is moved fromclosed position, the charge within the corresponding hopper is emptiedthrough the chute 21 into a coking chamber 11. In order that the hoppers19 of the lorr v car may be opened severally, an individual control isprovided for the several slides 20 ot the spective hoppers. This indiidual control includes an operating lever 23 for each slide 20 andindependently-operable gearing connections, indicated diagrammaticallyat 2st in Fig. 2, between the several operating levers 23 and theircorresponding slides 20. If desired the levers 23, as well as the othercontrol parts of the lorry car, may be grouped within the cab 25, inwhich the attendant in control of the car stands. The controlling lever26 for the extension sleeves 22 of the several chutes 21 is also mountedin the cab 25 the motion of said lever is transmitted by means ofappropriate gearing connections 27 between said lever and the severalextension sleeves 22 for the purpose of elevating or lowering saidsleeves in unison, it being understood that the operation of all thesleeves 22 is dependent upon the operation of the singleslecve-controiiing lever 26 In addition to the gas collectinpmain 15, asmoke main 28 is mounted on suitable sup ports 29 along the side of thebattery opposite to the collecting main 15. Preferably this smoke mainextends clear along the battery of ovens and is provided with an inlet30 opposite each coking chamber or oven 11. The construction of the sevv'al inlets 30 is designed to close these inlets automatically, when notin use for permitting smoke to enter the main 2S, and will l e explainedhe 'naiter.

M unted on the lorry car or truck, pro erably extending laterallytliereer {O pip-e or line 31 which may sired, be n'ovided. withexplosion caps respe tively located the opposite ends u: said pipe Iheseexplosion caps are convt-znicntly constructed of hinge: ooors adaptednormally to close the opposite onus of the smoke pipe but which readilopen the accumulation oi? an undue r, in said pipe.

In accordance with the present invention meats is provided for permittiiti snickel I i a coke oven or chum .r r, ii-

on to pass through ling in nuznl ,c with the s oi a chamber or oven andlead downwardly from the smoke pipe or tine 251.. The d or pipes o are,disposed in alternation with respect to the charg; ng devices or coalhog) )c rs. in Fig. l, to cooperate with the altecnaie smoke outlets .13of an oven chamber and to permit the smoke which collects oetween themounds of coal in the oven chamber to pass Ireely to the smoke pipe 9'from which it can be dis harged optionally into the sm ke main 28 orthecollectinn' main At their loner end the several branch pipes 3 areprovided with encircling sleeves or extensible parts 2734 which areadapted to be lowered in unison into smoke conveying position withrespect to the t-(nresi ionoin smoke outlets 13 of a coking chamber ovenwhenever said sleeves 34; are in rceistry with smoke outlets. For thisnuriiose each sleeve 2% is pivotally connected: by means of verticallinks 35, see Fig. 3, with arms fixed on a rock shaf 37, the hitterjourualed in suitable bearing 38 supported by the frame of the lorrycar. Also, fixed on the shaft 3'? is a crank arm 39 pivotally connectedat its upper end to link 4-0, the latter in turn being pivotallyconnected at its opposite end to an operating lever ll preferablylocated within the cab 25. With this construction the operation of thelever ll will rock the shaft 37 and through the connections 36, eiiect alowering or elevating movement of the several sleeves 3 in unison. maybe retained normally in elevated position by means of arms 42 also fixedon the shaft 37 but projecting oppositely from the arms 36 and providedadjacent their outer extremities with counter weights 43.

The smoke discharged through the smoke outlets 1.3 of coking chamber oroven 11 into the smoke pipe or flue 31 of the lorry car may. inaccordance with the invention, be discharged either into the smoke main28 or the collecting main 15, or into both of said mains simultaneouslyas desired. When sunoke is discharged into the collecting main 15, thelatter not only functions as a smoke main for permitting oil-take oi thesmoke, but also permits the smoke to pass, before its final discharge,through the usual byproduct recovery apparatus, where recovery may behad of valuable by-prodnets carried off with the smoke. In order toaccomplish this highly desirable control of the discharge of the smoke,the smoke pipe or line 31 is provided preferably at its opposite endswith coupling elements re spectively adapted to connect the collectingmain and the smoke main with said smoke pipe indepenuently oi eachother. At its end adjacent the smoke main, the smoke pipe is providedwith a branch pipe i l extendir therefrom in a horizontal plane and prov.ed with an outlet surrounded by a seat 4:6. Pivotally mounted at l? onthe seal; i6 is a coupling member or pipe union 48 having a verticalpassageway 1-9 adapted to communicate with the said outlet and ahorizontal passageway 50 adapted to communicate with one of the inlets30 of the smoke main. Each outlet 30 of the smoke main consistsessentially of a short pipe section 51 projecting within and with outsaid main and provided with an inclined inner edge against which apivoted closure is adapted normally to gravitate into position forclosing the outlet of the smoke main. The closure 53 is pivoted at itsupper end, as shown at 54, within the smoke main and is'shifted from itsnormally closed position, indicated by dotted lines in Fig. 4:, into anopen position, indicated by full lines in said figure, by means of thefollowing mechanism. Pivoted at its upper end, as shown at 55, beyondthe outer edge 56 of the pipe section 51 is a ring 5'? provided with aninwardly projecting cam 58 adapted to engage the closure 53 and shiftthe latter into open position on movement of the ring 57 toward theouter edge 56 of. the pipe section 51. Normally the ring 57 willgravitate away from If desired the several sleeves 3i the edge 56, intothe position shown in dotted lines in Fig. 4:, thereby permitting theclosure 53 to gravitate into the closed position hereinbeiore described.The opening movement of the ring 57 is accomplished by the vertical edge59 of the coupling member 18, which when the latter is lowered intocoupled position with the smoke main, as indicated in full lines in Fig.l, will engage said ring to shift the same inwardly and open the closureThus a positive and automatically operating means is provided forpreventing escape of smoke through any of the outlets 30, when thelatter are not in use.

The coupling member 4.8 is pivoted to the end of a link 60 extending toand pivoted at its opposite end to an operating lever 61, preferablylocated within the cab 25. If desired a crank arm 62 may be pivoted at63 on the link 60. The crank arm 62- is pivoted at its opposite end at64 and is provided with a counterweighted arm 65 for shifting the link60 to normally throw the coupling member 48 into its inclined orinoperative position, as indicated by dotted lines in Figs. 1 and l.This construction insures movement of the coupling member into aninoperative position when the smoke discharging operation has been conpleted and prevents its striking the pipe sections 51. during themovement of the lorry car on its track.

At its opposite end the smoke pipe 31 isprovided with a coupling memberadapted to make connection with the collecting main 15 in the event itis desired to discharge the smoke from the pipe 31 into said collectingmain. The pipe 31.is provided with a short branch 66 on the outer end ofwhich is pivoted the horizontal portion 6? or" a discharge pipe 68. Saidpipe 68 is "further provided with avertical portion 69 the outer end ofwhich is turned down, as at 70, so

that it may make proper connection with 1 an inlet 71 of the ascensionpipe 16 of an oven. The inlet 71 of such ascension pipe may be normallyclosed by a pivoted cover 72. When it is desired to direct the smokefrom the pipe 31 into the collecting main, the cover 72 of an ascensionpipe adjacent which the lorry car is stationed, is opened and the pipe68 is swung into position in which the turndown portion covers the inlet71 of the ascension pipe. This operation of the pipe permits the smoketo pass into the collecting main and any by-prod ucts contained in thesmoke will be recovered along with the gases discharged into said mainfrom the other ovens for the battery.

Suitable valves, 73, '74-, are provided for shutting oil the couplingmember 48 or the pipe 68 from the smoke pipe 31 whenever said member 48or pipe 68 is not in use.
